Does this mean you now have 2G or you have 2G more ram?

Typically, the rule of thumb is you need at least 1Mb more swap than you 
have actual ram. Something to do with system core-dumps, or some such. 
I forget exactly what the the reason was, but it's still a good idea to 
have more swap than physical memory, even if it's only a slightly larger.

Maybe it was hibernation or something like that.  Must go back and read 
up on it again
